But, sitting down with Mirror Sport at the Belgian Grand Prix, he made it clear he remains committed to Aston Martin's own ambitious project. And the former BMW Sauber engineer also offered a theory as to why his name has been linked with a return to the Hinwil-based squad.
He said: "I think a lot of this comes about because I worked there for a very long time. I have a lot of friends still there and I see these friends from time to time.
"Maybe there's an element of people could put one and one together - why is he in Switzerland? Because the godfather of my son is working there! If I have friends there, I cannot abandon my friends because of that.
"I have here the project of a lifetime, where you have someone investing so much to become a big team and to be part of that is an opportunity for everybody. So my focus is on this project, '25, and '26 is a huge challenge in front of us. That is where my thoughts are."
